Workshop: Future of Modeling in Composites Molding Processe;: June 9-10, 2004; Washington, DC

本次研讨会的目标是建立在复合材料成型制造过程中使用建模的愿景，确定实现这一愿景必须克服的当前障碍，并为克服这些障碍提供研究重点。其方法是举办一个有来自工业界、政府实验室和学术界的参与者参加的研讨会，该研讨会由国家科学基金会、美国能源部和美国塑料理事会共同主办，以解决与注塑成型短纤维和长纤维复合材料的建模、液体成型、压缩成型、热塑性液体成型和注塑-压缩成型相关的问题。聚合物复合材料由于具有优异的强度和刚度重量比，被广泛应用于航空航天、汽车等多个行业。为了充分实现聚合物复合材料在现代工程部件和系统中的优势，在设计过程的每一步都必须开发和应用建模方法。本次研讨会讨论了在聚合物复合材料产品设计中使用的建模和计算机模拟的作用，以及在其生产中使用的制造方法。由于改进了建模方法，设计周期将缩短，这将降低成本，并允许对市场变化做出更快的反应。新的应用程序将会出现。先进的建模策略将通过提供在生产中使用更少能源的更高效的设计来帮助解决环境问题，并提供机会更好地适应整个生命周期的产品需求，包括材料加工、生产、使用和处置。

The objective of this workshop is to establish a vision for the use of modeling in composite molding manufacturing processes, identify current barriers that must be overcome to realize this vision, and provide a research focus for overcoming these barriers. The approach is to hold a workshop with participants from industry, government laboratories and academia, that is co-sponsored by the National Science Foundation, the US Department of Energy, and the American Plastics Council to address issues related to the modeling of injection molded short and long fiber composites, liquid molding, compression molding, thermoplastic liquid molding, and injection-compression molding. Polymer composites are widely used in a variety of industries including Aerospace and Automotive because they provide outstanding strength and stiffness to weight ratios. To fully realize the benefits of polymer composites in modern engineering components and systems, it is imperative that modeling methods be developed and applied at every step in the design process. This seminar addresses the role of modeling and computer simulations that are used in the design of polymer composite products and the manufacturing methods used in their production. As a result of improved modeling approaches, design cycles will be shortened which will reduce costs and allow for faster responses to changes in the marketplace. New applications will emerge. Advanced modeling strategies will help address environmental concerns by providing more efficient designs that use less energy in production, and provide opportunities to better accommodate product requirements over the entire life cycle, including materials processing, production, use and disposal.
